Patients who have undergone private heart surgery may be glad to know that their health is unlikely to be affected by flying.
The British Cardiovascular Society has issued new guidance clarifying that the majority of heart patients are not risking their health by flying.
June Davison, senior cardiac nurse at the British Heart Foundation (BHF), explained: "Historically there's been some confusion about when and if people with heart and circulatory conditions can fly.
"These expert guidelines provide some clarity and show flying is safe for most people with heart and circulatory disease."
She did, however, warn those who have undergone recent surgery to check with their doctor before jetting off on their summer holidays.
Coronary heart disease is the UK's biggest killer affecting one in five men and one in seven women, according to the BHF.
Figures show that around 2.5 million people in the UK are living with heart disease.
